Allergies occur when the immune system mistakenly identifies a harmless substance (allergen) as a harmful one, triggering a response. Common allergens include pollen, dust mites, mold, pet dander, certain foods, and insect stings.
- Environmental Allergies: Caused by substances like pollen, dust, and mold.
- Food Allergies: Triggered by foods such as peanuts, eggs, or shellfish.
- Insect Sting Allergies: Caused by stings from bees, wasps, or other insects.
- Drug Allergies: Caused by reactions to medications.
Symptoms vary depending on the type of allergy and can include:
- Sneezing, runny nose, itchy eyes (for environmental allergens)
- Hives, swelling, or stomach issues (for food allergies)
- Breathing problems, wheezing, or anaphylaxis (severe allergic reactions)
- Avoiding Allergens: The most effective way to manage allergies is to avoid exposure to triggers.
- Medications: Over-the-counter antihistamines, nasal sprays, and decongestants can relieve mild symptoms. For more severe reactions, prescribed medications or epinephrine may be needed.
- Allergy Shots (Immunotherapy): For individuals with severe or persistent allergies, immunotherapy may help reduce sensitivity to allergens over time.
Anaphylaxis is a severe allergic reaction that
requires immediate attention. It can cause difficulty breathing, swelling, and loss of consciousness. Those at risk should carry an epinephrine auto-injector and seek emergency medical help.
- If symptoms worsen or do not improve with over-the-counter treatments.
- If anaphylaxis occurs, always use epinephrine and call 911 immediately.
